Graphics ikhadi Nvidia Geforce GTX 650 - Uphengululo iimpawu leengcali kunye nohlaziyo umsebenzisi

Ukukhetha ikhomputha okanye i-laptop, kuyafaneleka ukubeka ingqalelo kungekuphela kweso sixhobo esifakwe kwiprosesa, kodwa nokuba yiyiphi ikhadi levidiyo okanye i-speed accelerator. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kuyo kubadlali bebhola, abakhi bezakhiwo kunye nalabo abafuna umfanekiso kumboniso ukuba ube ngumgangatho ophezulu. Ngokuqinisekileyo, iliso lijongene nomgangatho womfanekiso, kodwa kungekhona nje kuphela, ngaphandle kwekhadi levidiyo elifanelekileyo, zonke izakhono zalo zingasetyenziswa.

Okwangoku, imarike inikeza iindidi ezahlukeneyo zevidiyo. Ukuphakama kweli nqanaba kubelwe phakathi kwe-AMD ne-NVIDIA. Nangona kucingwa ukuba iNVIDIA ilungile.

Kwimeko apho udinga ukhetho oluhle kakhulu lwebhajethi, olukwazi ukubonelela ngekhwalithi yekhwalithi ephezulu kunye nezixhobo ezifanelekileyo zekhompyutha, sincoma ukuba ukhangela i-adapter yevidiyo ye-NVIDIA Geforce GTX 650. Okokuqala, inexabiso elincinci xa kuthelekiswa "nabazalwana balo abadala". Nangona kuphantsi kwabo kumandla kunye nokusebenza kakuhle, kodwa, nangona kunjalo, kusebenza kakuhle.

Isakhelo se-accelerator

Isakhiwo sekhadi le-NVIDIA Geforce GTX 650 linje:

- inezigidigidi ezigidi ezili-13 zeengcingo;

Inkcazo ecacileyo ye-accelerator yevidiyo

Isiseko salolu hlobo lwee-accelerators zevidiyo liyaziwa ngevidiyo ebizwa ngokuba yi-GK107. Isebenza kumadivayisi amaninzi ephathekayo nakwikhadi lefayile yegraphic Geforce GT 640. Le divayisi inika inkxaso yonke impawu ekhoyo kwi-Geforce GT 640 ye-chipset efakwe kwi-Geforce GTX 680. Inayo yonke impawu zakhiwo zeKepler.

Le projekthi yemifanekiso iquka iqoqo elilodwa elibonelela nge-GPC. Iqukethe 2 SMX multiprocessors, ezibandakanya ii-384 zekhompyutha zokuhamba, kunye nama-modules angama-32. Ufikelelo lwe-128-bit lunikeza iseshoni ye-chipset ye-graphicset yekhadi levidiyo, esekelwe kwimimori ememori ye-64-bit. Umthetho wokulingana kunye nokubophezela kubalawuli beememori kubonisa ukufumaneka kweebhloko ezili-16 ezenza i-ROP imisebenzi ye-raster.

Ngokusekelwe kulo, ubuninzi beememori yevidiyo yasekhaya iNVIDIA Geforce GTX 650 - 1 okanye 2 GB. Ikhadi isebenza kwimizuzu engama-5 ye-MHz. Iyancitshiswa ngeemodareyitha ezithengisa kakhulu zevidiyo ezisekelwe kwiKepler. Isiphumo esiphumela sisiphumo esingu-80 Gb / s njengesiphumo kwaye sifaneleke ngokufanelekileyo kwisigqibo sebhajethi, kuba asifani nenye yekhadi elihlukileyo nelikhulu leGTX 650 Ti.

Njengamacebo axabisa kakhulu kulo mgca, i-NVIDIA Geforce GTX 650 ayinaso izixhobo zobugcisa ezixhasa ubugcisa be-GPU Boost. Le setethi yesisombululo sesofthiwe ivumela indlela yokuzenzekelayo ukwenzela ukwandisa iifom zokusebenza zeGPU ukwenzela ukubonelela ukusebenza ngokugqithiseleyo, ngelixa ukwandisa amandla okusetyenziswa. Yenza ukuba kube lula ukusebenza kwii-frequencies kwi-device, ukuvumela ukuba ungadluli ngaphaya kwe-pack pack yokushisa. Akubi, kulungile? Kodwa, ngelishwa, umvelisi wanquma ukuba amakhadi ohlahlo lwabiwo-mali ayiludingi lobu buchwepheshe. Ngaloo ndlela, ngokungafani nezixhobo ezinamandla, umzekelo, i-NVIDIA Geforce GTX 650 Ti, isantya se-clock standard ye- video chip, exhotyiswe kule fowuni, ifakwe-1058 MHz.

Nangona uhlahlo lwabiwo-mali, ikhadi levidiyo liyisisombululo esihle kakhulu sokuqinisekisa ukusebenza ngokuzinzileyo kwanenkqubo entsha yememori yeememori. Nayiphi na i-shooter ayiyi kuncipha ngeenkcukacha ezilungileyo kakhulu zomfanekiso kunye nombala we-graphicity of the graphics. Kwakhona kunakho ukubonelela ngomgangatho ophezulu wegeyimu yemidlalo yabadlali abaninzi, esebenza ngesiseko se-DirectX 11 nakwi- HD (1080 p) ifomathi.

Ezinye iimpawu zekhadi levidiyo

Ibhodi yesiphaluka yale dilesi yevidiyo isifutshane, ngoko ke ungafaka kuphela amafolisi amancinci kuwo. I-RSV imodeli eqhelekileyo ilula, ukuba uyayithelekisa kunye nezisombululo ezibizayo zalo mgca. Ubude bebhodi ngu-145 mm. Amandla angaphezulu anikezelwa ngumxhasi we-6-pin, kunye ne-GTX 660. Ukuveliswa kwesithombe kunokwenzeka kwiindlela ezintathu. Nangona kunjalo, ikhadi le-hardware linokuxhasa ukufikelela kwi-4. Ukuvelisa ulwazi lwevidiyo, ezimbini ze-DAL-link kunye ne-HDMI zixhobo.

Ngokusebenzisa i-GK107 GPU kule khadi, esetyenziswe kumadivayisi eselula, i-speed accelerator isebenzisa amandla amancinci kakhulu, nangona ifowuni isebenza kumaziko aphakamileyo. Kwimodi yokulala, ifowuni isebenzisa kuphela ama-watts amahlanu kuphela, kwaye xa idlala ividiyo ephakamileyo, i-watts 13 kuphela. Esi sibonakaliso sisona sifanelekileyo kule klasi. Imisebenzi enzima kakhulu idinga ukusetyenziswa kwamandla amaninzi, kwaye ubuninzi buyi 64 watts. Kodwa nangona xa usebenza ngokugcwele ngokupheleleyo, ifowuni ikhupha kakhulu ubushushu. Ngenxa yoko, umenzi washiya ikhonkco ye-pin-6 yamandla angaphezulu. Inika ithuba elihle lokugqithisa idivayisi, ukwandisa ukusebenza kwayo, kwaye linikezela ngokuzinzileyo kwe-adapter.

Amanye amaqabane enkampani akhiqiza eso sixhobo ngaphandle kwesixhakaxhaka esinika amandla angaphezulu. Ekubuyeleni, banikela ngezisombululo zefestile ezingaphezu kwexesha. Uninzi lwezi adapta zevidiyo, ezenziwe ngamashishini abalingani, zinamandla okugqithisa kunye nesantya esilingana ne-1100 MHz. Ukuba unqabile uNVIDIA Geforce GTX 650, ikhadi liya kunika ixesha elide ukuya ku-1200 MHz. Kukho imodeli eneenkqubo zokukhulisa amandla, ukupholisa, ukubonelela ngokufanelekileyo ukusebenza kwezixhobo.

Le khadi levidiyo lixhasa zonke iikhompyutheni zakamuva ezenziwe yiNVIDIA kumadivayisi abo. Le ngxelo i-PhysX, i-Adaptive VSync, njl. Umzekelo omtsha unikezela abathengi zikhetho ezikhoyo ngoku okwangoku - i-DirectX 11, i-TXAA, i-PhysX, i-VSync kunye neyezinye.

Ikhadi lemifanekiso ye-NVIDIA Geforce GTX 650 yindlela enhle kakhulu yokuphucula iinkqubo zevidiyo zabadlali bebhola kunye ne-DirectX 10 ephathekayo.

Iimpawu eziqhathaniswayo nale divayisi zivela kwiingcali

Ngaba le fowuni iyingozi okanye ingcono kunokuba ibengaphambili? Kwaye kungcono ukuthatha ntoni: i-adapter yevidiyo esuka kumqhubi-nkampani ye-AMD-okanye nangona kunjalo uNVIDIA Geforce GTX 650? Ukuthelekisa kuya kuphendula yonke le mibuzo.

1. Ukuthelekiswa kwezixhobo zomvelisi. Umenzi uqhathanisa ikhadi elitsha levidiyo kunye neGeforce 9500 GT (ixesha elidlulileyo). Ngaloo ndlela, kunokwenzeka ukuvavanya impumelelo yenkampani kule ndawo.

Xa udlala imidlalo efana neWorld Warcraft: Izixhobo zePandaria, isiqhelo sichaza amaxesha angama-4 ukusebenza kakuhle kunekhadi ekuthelekiswa ngayo. Xa uqala uMax Payne 3 umphumo uyafana. Ikhadi elikhulileyo alikwazi ukukhuphisana neliveli nangona usebenza kwiPoftware ye-software ye-DirectX 9.

Kwenzeka okufanayo xa uhlola ukusebenza kwezi zixhobo kuMechWarrior Online. Umdala akakwazi ukukhuphisana nophuhliso olusanda kutsha lweNVIDIA. Ivelisa iifom ezili-10 kuphela ngesibini, xa entsha-40.

2. Ukuthelekisa kunye nezixhobo ezitsha zodidi olufanayo. Masiqhathanise ne-accelerator yomgca wangaphambili, okwehlu lodidi olufanayo - iGeforce GTS 450. Esi sixhobo sisekelwe kwi-GPU kwaye sinokuxhasa i-DirectX 11.

Ngalo mzekeliso, umphumo ulungile. Ukusebenza kwesoveli ku-20% ephezulu kunomzekelo owenziweyo. Inesibonakaliso esinamandla kakhulu sokusebenza kwamandla. Le nzuzo inikwe iteknoloji entsha, engekho kumzekelo omdala, - iKepler. Ngenxa yoko, ukusebenza ngeyunithi yamandla asetshenzisiweyo kwisixhobo sethu kufana kabini phezulu.

3. Ukuthelekisa kunye namacebo anamhlanje avela kumncintiswano. Umncintiswano omkhulu we-NVIDIA Geforce GTX 650, enezobuchwepheshe bwanamhlanje, yi-AMD Radeon HD 7750. Kodwa le fowuni, njengabanye, ilahla emva kwesigxina se-NVIDIA. Kwaye nangona kunjalo ukuba i-adapter yevidiyo ayinayo iteknoloji ye-GPU Boost, eyenza ikwazi ukunyusa ngokuzenzekelayo imvama yokusebenza ye-GPU. Kodwa nangaphandle kwale teknoloji, ikhadi levidiyo ukusuka ku-NVIDIA linamaqondo angama-1200 MHz kwaye ngaphezulu, ngelixa umncintiswano unama-1058 MHz kuphela. Njengoko ubona, nangona ixabiso leNVIDIA Geforce GTX 650 liphezulu, Ngaphandle komncintiswano walo, amandla ayo kunye nempawu ezingaphezulu kokugqithisa lo mmahluko.
